SM Higgs production via Weak Boson Fusion and Decay

1
SM Higgs production via Weak Boson Fusion and
Decay
Quarks from incoming protons irradiates W?/Z0.
Annihilation of those produces Higgs boson,
which is accompanied with two high energetic
jets, going to the forward direction (? - 3 to
5). Detecting and tagging of those jets
will help significantly reduce QCD background.

Higgs boson decay
Important decay modes for SM Higgs with the
mass 300GeV and up are decays through W/Z bosons
pairs and t quarks. Higgs boson production
simulation via WBF, forward and central jets
detailed reconstruction, leptons careful
identification, missing transverse energy
precise measurement will lead to the Higgs boson
discovery.

Status of investigation
Preliminary studies with CMS fast simulation
programs shows promising results about Higgs
discovery potential via WBF.

Forward jets are used to lower the background
and select WBF processes.
Missing transverse Energy is used to lower
background and to reconstruct the transverse mass
